What are the advantages of a client-server network model?

• A. Central management of the server, security, and easier organization/management of resources
• B. Low cost
• C. High availability
• D. No maintenance

Answer: (A)

Centralized control and security are the main benefits of a client-server network. In this setup the server acts as the hub for services like authentication, access control, file and resource sharing, applications, printing, backups, and policy enforcement. Administrators configure users, groups, permissions, and security rules in one place, which makes it much easier to manage who can access what and to apply consistent policies across the entire network. Because resources and services are centralized, backups, software updates, and activity logging are handled from a single point, simplifying monitoring and accountability. Clients stay relatively simple—they request services from the server, which reduces configuration effort on each workstation and supports scalable growth as more users and devices join the network. While some environments can build in high availability or lower ongoing costs, those outcomes depend on specific architectures and investments; they are not automatic guarantees of the client-server model. Maintenance is still required to keep the server secure, up-to-date, and reliably backed up.
